2 Edward L. Greene. 
Lake region in south western Oregon by Mr. J. B. Leiberg in 1894, 
and distributed under no. 651. The best specimen seen is on sheet 
287 488, U. S. Herbarium. 
20. Aconitum platysepalum Greene, nov. spec. 
Caulis 5 dm altus, firmiter erectus, teres, inferne sparsim et minutim 
puberulus, superne villosulus; folia inferiora longe petiolata, superiora 
multo minora subsessilia, omnia pallida, glabriuscula, 5-partita, segmentis 
profunde 5-lobis; racemus laxus, circa 5-florus, pedicellis rigidiusculis 
adscendentibus; flores mediocres, saturate caerulei; sepala anteriora 
brevia, late et oblique cuneiformia, apice valde dilatata et oblique trun- 
cata; sepali posterioris sacco perbrevi obtuso, rostro subulato magno 
horizontali. 
South side of Mt. Shasta, northern California, H. E. Brown, 
July, 1897. A plant of peculiar aspect, and unusual floral structure, 
espicially as to the broadly dilated and truncate lower sepals. The axils 
of the upper haves are bulbiferous, yet the plant is by no means next 
of kin to A. bulbiferum Howell, that being a weak slender partly reclining 
if not trailing species, with very different flowers. 
21. Aconitum viviparum Greene, nov. spec. 
Caulis tenuis erectus simplex, 4—7 cm altus, teres, infra inflores- 
centiam glaberrimus; folia inferiora longe petiolata, superiora sessilia, 
omnia tenuia laete virentia et superne puberula, segmentis subrhomboideis 
profunde incisis; racemus vel pauciflorus vel floribus carens et omnino 
bulbilliferus; flores dum adsint-magni atropurpurei, sepalis anterioribus 
oblongo-linearibus obtusiusculis, sepalo posteriore elato sacco lato rotun- 
dato et rostro subulato horizontali valde prominente praedito. 
This interesting species is known only from marshes about crater 
Lake, at the summit of Mt, Pitt, southern Oregon, and it may be local 
there. Specimens of it were distributed by Mr. Cusick, under no. 2972, 
and the name A. bulbiferum Howell, which this plant can not be. These 
specimens show plants with a good raceme of haudsome flowers, and 
no bulblets except in the axils of lower leaves, Others obtained at the 
same station by Coville and Leiberg in 1896- (no. 395) display no 
flowers at all, but a spike of bulblets instead, the bulblets often partly | 
under cover of redueed sepals, thus indicating that the ovaries of the 
flowers were transformed into bulblets without obliterating the other 
floral organs. 
22. Aconitum geranioides Greene, nov. spec. 
Planta metralis et verisimiliter ultra, caule gracili, tortuoso, superne 
sparsim ramoso, laxiuscule paucifloro; folia ampla, longe petiolata, petiolis 
gracilibus plus minus tortuosis, lamina 10—15 cm lata, fere usque ad 
basim 5-divisa, segmentis late cuneato-obovatis, profunde incisis, lobis 
oblongo-lanceolatis, acutis, interdum subfalcatis, integris vel breviter in-. 
cisis; flores vix mediocres, saturate caerulei; sepala anteriora brevia, " 
ovalia, obtusa; galea sepali posterioris elata, angusta, rostro magno q 
obtusiuseulo modice prominente; folliculi erecti, glabri, nitentes.
